DEPRECATED -- Please use ForceGL20 instead.
Old descriptionThis is a one-mixin mod for 1.17+ that should allow people to use an older version of OpenGL with Minecraft. This is a temporary workaround for people with older computers (2010 and older or so) to play on 1.17, if they were able to play on 1.16. It will still use a newer version if supported, but if it's not supported, it will fall back to 3.1 at the earliest.
Disclaimers
WARNING! This may be slightly unstable, and some resource packs and/or mods may not work. It should work with Sodium, but no guarantees. Incompatibilities will not be fixed.
